- Akışın **cache'lenmesini önlemek** için `Cache-Control: no-cache` header'ını ayarlar.
- Nginx gibi bazı proxy'lerde **buffering'i önlemek** için özel `X-Accel-Buffering: no` header'ını ayarlar.

- Устанавливать заголовок `Cache-Control: no-cache`, чтобы предотвратить кэширование потока.
- Устанавливать специальный заголовок `X-Accel-Buffering: no`, чтобы предотвратить буферизацию в некоторых прокси, например Nginx.

- 當 15 秒內沒有任何訊息時，傳送一次**「保活」`ping` 註解**，以避免某些代理伺服器關閉連線；此作法源自於[HTML 規範：Server-Sent Events](https://html.spec.whatwg.org/multipage/server-sent-events.html#authoring-notes)中的建議。
- 設定 `Cache-Control: no-cache` 標頭，以**防止快取**串流內容。
- 設定特殊標頭 `X-Accel-Buffering: no`，以**避免**在像 Nginx 這類代理中被**緩衝**。
